Are you definitely sure that it's the newly-built lfs-7.9 kernel that is panicking. Did you build lfs-7.9 on this same system? Has the hardware config changed since you built it? Have you moved the lfs-7.9 hd to a different physical connector on the same - or a different - machine? Is the lfs-7.9 disk on a sata or usb or esata or what, connector? What is the diff between the kernel config on the lfs-7.9 build-host, and the lfs-7.9 kernel. Am wondering - maybe a long shot - if you've got some add-on chip that's controlling the lfs-7.9 disk, while the other disks are using native-chipset ports. > I fought several battles with grub2 and udev.

What are the diffs between the configs for the ok 7.7/7.8 kernels, versus the not-ok 7.9 kernel? Also diff between sorted configs, if that helps. What is your grub cfg that contains entries for the ok 7.7/7.8 kernels and the not-ok 7.9 kernel? akh > > Thank you and keep up the good work.
